On Improving 5G Internet of Radio Light Security Based on LED Fingerprint Identification Method

Abstract

In this paper, a novel device identification method is proposed to improve the security of Visible Light Communication (VLC) in 5G networks. This method extracts the fingerprints of Light-Emitting Diodes (LEDs) to identify the devices accessing the 5G network. The extraction and identification mechanisms have been investigated from the theoretical perspective as well as verified experimentally. Moreover, a demonstration in a practical indoor VLC-based 5G network has been carried out to evaluate the feasibility and accuracy of this approach. The fingerprints of four identical white LEDs were extracted successfully from the received 5G NR (New Radio) signals. To perform identification, four types of machine-learning-based classifiers were employed and the resulting accuracy was up to 97.1%.

Target 5G visible light positioning signal subcarrier extraction method using particle swarm optimization algorithm

“…When the receiver captures real-time PRSs powers of each LED, the corresponding environment indexeŝ λ will be predicted by the classification model M shown in equation (7). As the distances between receiver and each LED have been figured out, the set of distancesD is used to estimate the coordinate of the receiver(x,ŷ,ẑ) by RSSI trilateration, shown in equations ( 8) to (13).…”

“…Research [12] presented a multilayer network architecture by integrating visible light communication(VLC) and VLP within 5G networks, in order to guarantee the diverse IoT requirements. In study [13], a device identification method integrates VLC-based communication, In order to adapt the intensity modulation and direct detection(IM/DD) and keep a high spectrum efficient in VLC , the orthogonal frequency-division multiplexing (OFDM)based modulation schemes are widely used to generate the real and non-negative positioning signals. In 5G New Radio(NR) frame of IoRL, a total of 192 subcarriers are used to carry PRSs.…”

Flexible Quantum Dot Light‐Emitting Device for Emerging Multifunctional and Smart Applications

“…[ 1,2 ] EL devices, which can offer light to brighten/interact with the environment/human as light sources and directly transmit information to visual system as displays, is an indispensable and core part of human lives. Furthermore, with the development of the Internet of Things (IoT) [ 3–5 ] and 5G [ 6,7 ] technologies, lighting emitting devices play an increasingly pivotal role, beyond display and lighting, in emerging fields such as optical communication, wearable electronics, and integrated health.

In-Vehicle Visible Light Communications Data Transmission System Using Optical Fiber Distributed Light: Implementation and Experimental Evaluation

“…In this area, VLC technology proved capable of ensuring tens of gigabits per second data rates [10], with connections above 100 Gb/s being envisioned [11]. Consequently, VLC began being considered a very promising candidate in 5G-6G applications [12][13][14][15][16]. In this area, VLC is extremely suitable due to the spatial reuse capabilities that recommend it for the small cell concept.…”
